Why Your Furnace Could be Blowing Cold Air Published on October 21, 2016 You listen to your furnace kick on and you’re expecting a cozy blast of warm air, but instead all you feel is cool air blowing. That’s not preferable in the freezing weather! There are a few reasons why your heating system could be blowing cold air. Norrell Service Experts Heating & Air Conditioning is here with a few of them to help you find the culprit. Thermostat It could sound silly, but the thermostat is where you should start. It’s the starting point for any heating technician, too. Confirm the system is set to “auto and not “on.” If the thermostat is set to “on” then your heating system will blow constantly, even when it is not actually heating the air being produced, thus putting off cold air. Flipping it to “auto” will make sure the heating equipment only blows when it’s truly heating the air to keep your home warm and cozy. Air Filter Most air filters need to be changed monthly to keep them from growing dirty and clogged. If air filters aren’t swapped out often enough, the clogged air filter may impede airflow into your heating equipment. If this occurs, it can overheat your equipment, causing the equipment to stop heating as a safeguard. Duct Work If your duct work contains leaks, connection issues, or was not designed correctly, it could allow warm air from the furnace to seep out. This would not only cause your heating equipment to give off cold air, it could significantly run up your energy bills since your heating equipment is heating non-living space, and will have to work harder to keep your home warm. There are multiple other reasons that your heating system could give off cold air.
